LCD device with multi-domain vertical orientation mode

Abstract

The invention relates to a liquid crystal display device of polydomain vertical orientation mode, comprising a first substrate and second substrate oppositely disposed; a liquid crystal layer between the first substrate and second substrate; a pixel electrode formed on the first substrate; a common electrode formed on the second substrate; a groove or protrusion graved on the pixel electrode or common electrode; a first protrusion and second protrusion alternatively oppositing to the said groove or protrusion on the pixel electrode or common electrode; the first protrusion having first height and the protrusion having second height and the first height is higher than the second height and the first protrusion being alternatively arranged with the second protrusion. The liquid crystal display device can realize 8-domain display without increasing the drive cost and reducing the production good ratio, in order to improve the aberration.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device in a multi-domain vertical alignment mode. Background technique [0002] Liquid crystal display (LCD) occupies an important position in flat panel display devices due to its advantages of low energy consumption and thinness. A liquid crystal display device is usually composed of a backlight module, a first substrate and a second substrate oppositely arranged, and a liquid crystal layer filled between the first substrate and the second substrate. The liquid crystal layer is composed of liquid crystal molecules, and the display area on the second substrate includes A plurality of pixel areas, in which thin-film transistors (TFT) and pixel electrodes are arranged, and the thin-film transistors serve as switching elements; alignment films are formed on the inner sides of the first substrate and the second substrate to align liquid crystal molecules; p...

Problems solved by technology

The method of capacitive coupling can improve the chromatic aberration, but it is easy to accumulate charges at both ends of the coupling capacitor, which will cause afterimages and affect the display effect

However, the double TFT S-PVA mode needs to manufacture two TFT devices, and doubles the number of gate or data lines, which reduces the manufacturing yield to a certain extent and increases the driving cost.
